However, if they are left there and a major earthquake occurs, which could happen at any time, the entire structure might collapse, which could make removing the fuel rods impossible, and could cause too much nuclear material to come into contact and might lead to a meltdown, partial or complete. That would be a disaster of unknown proportions.
Clearly, removing the fuel rod assemblies before that happens is a better choice, which is what they're about to begin. The process has been planned and tested in a limited way. Now, they think they're ready to remove the fuel rod assemblies, which will be stored in storage pools somewhere on the site. If they are successful, the danger of the structure collapsing will be eliminated. Even if there are problems, if they can remove the bulk of the fuel rod assemblies, the danger will be drastically reduced.
The area is still heavily contaminated, of course. The project is quite hazardous and there are still unknown factors.
